    This mill assimilates the advanced technology from Germany and Japan. It is derived from the high pressure grinder mill to produce the fine powder particularly. This high pressure micronizer succeeded in solving the traditional problem of classification. High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.

  • Mill (grinding)Wikipedia

    A mill is a device that breaks solid materials into smaller pieces by grinding crushing or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g. via a hand crank) working animal (e.g. horse mill) wind or water (). This type of mill offers the minerals industry numerous benefits Safe process technological design. Low operating expenses in comparison to other systems both the power consumption and the costs for wear parts are significantly lower. High throughput rates a high-pressure grinding roll can replace several reduction crushers.
